katarina nerfs??

Katarina is strong in the early and mid game. She falls off in the later stages of the game.

Its like you complaining about Renekton being strong in the early and mid game. Most assassins right now got this problem. Katarina won't see nerfs because she's quite balanced right now.

I've been spaming her a lot (albeit in normals) and I think I've only seen her banned once or twice. People seem to think she's some team fight goddess but, honestly, the team fight aspect is the hardest thing to execute in her kit in late game.

Learn to play against her. If you can't, then that must say something about your ability to play.
